Polythematic, partly imitative, but mostly free polyphony waywardness of polyphony matches the mood of the mode. Languid. Proceeds without break. Theme 1 is once stated incipit. Followed from 8-28 with imitations of motivic theme 2. Remainder of work is free with varied texture in phrases which explore the harmonic area. Textures from homophonic to redoble. Dissonance enhances work esp. final cadence at 85-87.
Harmonic progress, registration, texture control musical drama.
